DEACONS AND LIGHTS
In our church, we have someone that does the maintenance and replaces light bulbs and things like that. They do not want their pastor to do this for two good reasons:
1) I know very little about maintenance, and my church knows that I know very little.
2) They don't want the lights to be bright at the expense of the sermons being dull.
That's what a deacon is all about: serving that a pastor might fulfill his calling.
